In this chapter you will:
(1) Explain the meaning of cost and how costs are assigned to products and services.
(2) Define the various costs of manufacturing products and providing services as well as the costs of selling and administration.
(3) Prepare income statements for manufacturing and service organizations.
One of the most important tasks of managerial accounting is to determine the cost of products, services, customers, and other items of interest to managers. Therefore, we need to understand the meaning of cost and the ways in which costs can be used to make decisions, both for small entrepreneurial businesses and large international businesses. Cost is the amount of cash or cash equivalent sacrificed for goods and/or services that are expected to bring a current or future benefit to the organization.
As costs are used up in the production of revenues, they are said to expire. Expired costs are called expenses. On the income statement, expenses are deducted from revenues to determine income (also called profit). We can look more closely at the relationship between cost and revenue by focusing on the units sold. The revenue per unit is called price.
Accumulating costs is the way that costs are measured and recorded. The accounting system typically does this job quite well. When the company receives a phone bill, for example, the bookkeeper records an addition to the telephone expense account and an addition to the liability account, Accounts Payable. In this way, the cost is accumulated.
Assigning costs is the way that a cost is linked to some cost object. A cost object is something for which a company wants to know the cost. For example, of the total phone expense, how much was for the sales department, and how much was for manufacturing? Assigning costs tells the company why the money was spent. In this case, cost assignment tells whether the money spent on phone calls was to support the manufacturing or the selling of the product.
Managerial accounting systems are structured to measure and assign costs to entities called cost objects. A cost object is any item such as a product, customer, department, project, geographic region, plant, and so on, for which costs are measured and assigned.
Costs can be assigned to cost objects in a number of ways. The choice of a method depends on a number of factors, such as the need for accuracy. The objective is to measure and assign costs as well as possible, given management objectives.
For which business activities do we need an estimate of cost? Let’s take a minute to explore this topic in the You Decide case. Assume you are the Chief Financial Officer for a major airline company. Managing the company’s numerous costs is critically important in this fiercely competitive industry. Therefore, one of your major tasks is deciding which costs to manage in order to achieve the company’s profitability targets. In other words, you must identify the airline’s most important cost objects to track, measure, and control. Which cost objects would you select as critical to the company’s success?
Certain airline cost objects are obvious, such as the cost of operating a flight, which includes jet fuel and labor costs.
When an airline operates multiple types of aircraft, it incurs additional costs to train workers and store spare parts for each aircraft type.
Airlines might be even more specific with certain cost objects, such as when they focus on the cost per available seat mile (CASM).
Cost of managing crises is also an important cost object.
Finally, you might consider the cost object of processing customers, such as loading and unloading passengers and their baggage on and off of flights.
Like any company, an airline can identify and manage any cost objects it so desires. Sometimes the most difficult part of effective cost management is the first step—deciding on the exact items for which one needs to understand the cost. Mistakes in selecting the cost objects almost always lead to poor decisions and subpar performance.
Direct costs are those costs that can be easily and accurately traced to a cost object. When we say that a cost is easy to trace, we often mean that the relationship between the cost and the object can be physically observed and is easy to track. The more costs that can be traced to the object, the more accurate are the cost assignments.
Indirect costs are costs that cannot be easily and accurately traced to a cost object. Allocation means that an indirect cost is assigned to a cost object by using a reasonable and convenient method. Since no clearly observable causal relationship exists, allocating indirect costs is based on convenience or some assumed causal linkage.
Direct and indirect costs occur in service businesses as well. Some businesses refer to indirect costs as overhead costs or support costs. This slide shows examples of direct and indirect costs being assigned to cost objects.
In addition to being categorized as either direct or indirect, costs often are analyzed with respect to their behavior patterns, or the way in which a cost changes when the level of the output changes.
Variable cost: A variable cost is one that increases in total as output increases and decreases in total as output decreases.
Fixed cost: A fixed cost is a cost that does not increase in total as output increases and does not decrease in total as output decreases.
Opportunity cost: An opportunity cost is the benefit given up or sacrificed when one alternative is chosen over another.

Opportunity cost: An opportunity cost is the benefit given up or sacrificed when one alternative is chosen over another.
Output represents one of the most important cost objects. There are two types of output: products and services. Products are goods produced by converting raw materials through the use of labor and indirect manufacturing resources, such as the manufacturing plant, land, and machinery. Televisions, hamburgers, automobiles, computers, clothes, and furniture are examples of products.
Services are tasks or activities performed for a customer or an activity performed by a customer using an organization’s products or facilities. Insurance coverage, medical care, dental care, funeral care, and accounting are examples of service activities performed for customers. Car rental, video rental, and skiing are examples of services where the customer uses an organization’s products or facilities.
Services differ from products in many ways, including:
Services are intangible: In other words, the buyers of services cannot see, feel, hear, or taste a service before it is bought.
Services are perishable: Put another way, services cannot be stored for future use by a consumer but must be consumed when performed. Inventory valuation, so important for products, is not an issue for services. Because service organizations do not produce and sell products as part of their regular operations, they have no inventory asset on the balance sheet.
Services require direct contact between providers and buyers: Let’s consider an eye examination, for example. It requires both the patient and the optometrist to be present. However, producers of products need not have direct contact with the buyers of their goods. Thus, buyers of automobiles never need to have contact with the engineers and assembly line workers that produced their automobiles.
Managerial accountants must decide what types of managerial accounting information to provide to managers, how to measure such information, and when and to whom to communicate the information. For example, when making most strategic and operating decisions, managers typically rely on managerial accounting information that is prepared in whatever manner the managerial accountant believes provides the best analysis for the decision at hand.
There is one major exception. Managerial accountants must follow specific external reporting rules (i.e., generally accepted accounting principles) when their companies provide outside parties with cost information about the amount of ending inventory on the balance sheet and the cost of goods sold on the income statement. In order to calculate these two amounts, managerial accountants must subdivide costs into functional categories: production and period (i.e., nonproduction).
Product (manufacturing) costs are those costs, both direct and indirect, of producing a product in a manufacturing firm or of acquiring a product in a merchandising firm and preparing it for sale. Therefore, only costs in the production section of the value chain are included in product costs.
Product costs are inventoried. Product costs initially are added to an inventory account and remain in inventory until they are sold, at which time they are transferred to cost of goods. Product costs can be further classified as direct materials, direct labor, and manufacturing overhead.
Direct materials are those materials that are a part of the final product and can be directly traced to the goods being produced. The cost of these materials can be directly charged to products because physical observation can be used to measure the quantity used by each product. Materials that become part of a product usually are classified as direct materials.
Direct labor is the labor that can be directly traced to the goods being produced. Physical observation can be used to measure the amount of labor used to produce a product. Those employees who convert direct materials into a product are classified as direct labor. A company can also have indirect labor costs. Indirect labor is included in overhead and, therefore, is an indirect cost rather than a direct cost.
All product costs other than direct materials and direct labor are put into a category called manufacturing overhead. In a manufacturing firm, manufacturing overhead also is known as factory burden or indirect manufacturing costs. Costs are included as manufacturing overhead if they cannot be traced to the cost object of interest (e.g., unit of product). The manufacturing overhead cost category contains a wide variety of items. Examples of manufacturing overhead costs include depreciation on plant buildings and equipment, janitorial and maintenance labor, plant supervision, materials handling, power for plant utilities, and plant property taxes.

The total product cost equals the sum of direct materials, direct labor, and manufacturing overhead:
Total product post = Direct materials cost + Direct labor cost + Manufacturing overhead cost
The unit product cost equals total product cost divided by the number of units produced:
Per-unit Cost = Total Product Cost ÷ Number of Units Produced
Now let’s look at CORNERSTONE 2-1 which shows how to calculate total product cost and per unit product cost.
Product costs of direct materials, direct labor, and manufacturing overhead are sometimes grouped into prime cost and conversion cost:
Prime cost is the sum of direct materials cost and direct labor cost. Prime cost = Direct materials + Direct labor
Conversion cost is the sum of direct labor cost and manufacturing overhead cost. Conversion cost = Direct labor + Manufacturing Overhead
Now let’s look at CORNERSTONE 2-2 and see how to calculate prime cost and conversion cost both in total and per unit for a manufactured product.
As you go through the problem, remember that prime cost and conversion cost cannot be summed to obtain total product cost. This is because direct labor is included in BOTH prime cost and conversion cost.
The costs of production are assets that are carried in inventories until the goods are sold. There are other costs of running a company, referred to as period costs, that are not carried in inventory. Thus, period costs are all costs that are not product costs (i.e., all areas of the value chain except for production). The cost of office supplies, research and development activities, the CEO’s salary, and advertising are examples of period costs. In a manufacturing organization, the level of period costs can be significant and controlling them may bring greater cost savings than the same effort exercised in controlling production costs.

Period costs typically are expensed in the period in which they are incurred. However, if a period cost is expected to provide an economic benefit (i.e., revenues) beyond the next year, then it is recorded as an asset (i.e., capitalized) and allocated to expense through depreciation throughout its useful life. For example, the cost associated with the purchase of a delivery truck is a period cost that would be capitalized when incurred and then recognized as an expense over the useful life of the truck.

All costs associated with research, development, and general administration of the organization that cannot reasonably be assigned to either selling or production are administrative costs. General administration has the responsibility of ensuring that the various activities of the organization are properly integrated so that the overall mission of the firm is realized. Examples of general administrative costs are executive salaries, legal fees, printing the annual report, and general accounting. Research and development costs are the costs associated with designing and developing new products and must be expensed in the period incurred.

As with product costs, it is often helpful to distinguish between direct period costs and indirect period costs. Indirect labor is included in overhead. Service companies are also interested in distinguishing between direct period costs and indirect period costs. Although these costs do not affect the calculation of inventories or COGS for service companies, their correct classification nonetheless affects numerous decisions and planning and control activities for managers. For service firm like a restaurant, the chef’s salary would likely be classified as a direct period expense, but since the exact number of disposable napkins per individual meal served could not be easily determined, the cost of disposable napkins would be considered indirect, or overhead and napkin costs would be allocated, rather than traced, to individual meals served.

The cost of goods manufactured represents the total product cost of goods completed during the current period and transferred to finished goods inventory. The cost of direct materials used in production can be derived using the following formula: Beginning inventory of materials plus purchases minus direct materials used in production equals ending inventory of materials. Once the direct materials are calculated, the direct labor and manufacturing overhead for the time period can be added to get the cost of goods manufactured for the period. This is calculated as: Cost of goods manufactured = Direct materials used in production + Direct labor used in production + Manufacturing overhead costs used in production + Beginning WIP inventory - Ending WIP inventory

Now let’s look at CORNERSTONE 2-3 and how to calculate direct materials used in production.
Once the direct materials are calculated, the direct labor and manufacturing overhead for the time period can be added to get the total manufacturing cost for the period. The second type of inventory—work in process (WIP) is the cost of the partially completed goods that are still on the factory floor at the end of a time period.
WIP units have been started, but not finished; they have some value, but not as much as they will when they are completed; and there are beginning and ending inventories of WIP.
We must adjust the total manufacturing cost for the time period for the inventories of WIP.
When that is done, we will have the total cost of the goods that were completed and transferred from work-in-process inventory to finished goods inventory during the time period.

Now let’s look at CORNERSTONE 2-4 to see how to calculate the cost of goods manufactured for a particular time period.
Notice that the direct materials used in production is equal to the beginning materials in inventory plus purchased materials minus the ending materials in inventory.
To meet external reporting requirements, costs must be classified into three categories: (1) Production, (2) Selling, and (3) Administration. Cost of goods sold represents the cost of goods that were sold during the period and, therefore, transferred from finished goods inventory on the balance sheet to cost of goods sold on the income statement (i.e., as an inventory expense). Cost of goods sold is calculated as: Cost of goods sold = Beginning finished goods inventory + Cost of goods manufactured - Ending finished goods inventory.

Now let’s look at CORNERSTONE 13-5 which shows how to calculate the cost of goods sold.
Now let’s look at CORNERSTONE 13-5 which shows how to calculate the cost of goods sold.
The ending inventories of materials, WIP, and finished goods are important because they are assets and appear on the balance sheet (as current assets). The cost of goods sold is an expense that appears on the income statement. Selling and administrative costs are period costs and also appear on the income statement as an expense. As this diagram shows, there is a flow of manufacturing costs (direct materials, direct labor and manufacturing overhead) through the three inventories (materials, work in process, and finished goods) and finally, into cost of goods sold.
It is important that all sales revenue and expenses attached to a time period appear on the income statement. In the following Cornerstone example 2-6, notice that the heading tells us what type of statement it is, for what firm, and for what period of time. Also note that in the income statement, expenses are separated into three categories: production (cost of goods sold), selling, and administrative. Sales revenue is calculated as: Sales revenue = Price x Units sold

Now let’s look at CORNERSTONE 2-6 to see how the traditional format of the income statement is prepared for the manufacturing firm- BlueDenim Company.
Gross margin is the difference between sales revenue and cost of goods sold: Gross Margin= Sales Revenue – Cost of Goods Sold. It shows how much the firm is making over and above the cost of the units sold. Gross margin does not equal operating income or profit. Selling and administrative expenses have not yet been subtracted. However, gross margin does provide useful information. If gross margin is positive, the firm at least charges prices that cover the product cost.

A company can compare gross margin percentage with the average for its industry to see if its experience is within the ballpark range for other firms in the industry. Gross margin percentage varies significantly by industry. Gross margin percentage is calculated as: Gross Margin Percentage = Gross Margin ÷ Sales Revenue
Now let’s look at CORNERSTONE 2-7 to gain a better understanding of how to calculate the gross margin percentage for BlueDenim Company, along with the percentage of sales revenue for each line on the income statement.
In a service organization, there is no product to purchase, like in a merchandising or manufacturing operation. As a result, there are no beginning or ending inventories and no cost of goods sold and gross margin on the income statement. The cost of providing services appears along with the other operating expenses of the company.
